Calendar permissions across Exchange 2010 organisations.

We have three active directory forests with trusts between all three domains. We have three Exchange organisations. Users can see free/busy information across the organisations.

(This is due to a company merger - eventually we will all be on the one environment)

Is it possible to give users access to each others calendars to edit, cross organisations. i.e. the CEO wants her PA to be to be able to edit her calendar - however they are in different Exchange 2010 organisations / different Active Directory domains.

Trust is one thing on the AD level. For your exchange environments to talk to each other you will have to set up federation.
